Definitions

  • This application relates to a window air conditioning unit, wherein the scroll, or housing surrounding the evaporator blower, is formed of two pieces, such that a first piece can be removed and a sub-assembly of the motor, the blower and the condenser fan can be removed as a single item.
  • Window air conditioning units typically include a single housing enclosing a compressor, a condenser, an evaporator, and a fan or blower moving air over both the condenser and the evaporator.
  • a single motor rotates to drive both a blower for moving air over the evaporator, and a fan for moving air over the condenser.
  • the blower housing or "scroll housing” surrounds the blower, and provides a mount structure which closely surrounds a drive shaft for the blower.
  • the motor can be positioned in the outside space with its shaft extending through the opening in the scroll housing, and such that the blower can be on the inside space.
  • the scroll housing is positioned to direct air driven by the blower over the evaporator, and radially outwardly into a discharge conduit.
  • the scroll housing for surrounding the blower is provided as two pieces. This facilitates the removal of one piece and allows the sub-assembly of the fan motor and blower to be removed as a one-piece item for maintenance and repair.
  • the scroll housing is provided as two pieces. A first upper piece is removed, and then a sub-assembly of a fan, motor and blower can be removed as a one-piece item.
  • Figure 1 shows a window air conditioning unit.
  • Figure 2 shows the disassembly of a scroll housing portion, and the removal of a sub-assembly thereafter.
  • Figure 3 shows a detail of the scroll housing and its two pieces.
  • Figure 5 shows a locking feature
  • Figure 1 shows the window air conditioning unit 20 including a compressor 22 for compressing a refrigerant and delivering it downstream to a condenser 24.
  • a fan 26 moves air over the condenser 24.
  • a motor 28 drives the fan 26 and also drives a blower 30.
  • Blower 30 pulls air through a front grill 34 and openings 38, and across an evaporator 32.
  • a shaft 52 extends through a scroll housing 50 to drive the blower 30.
  • the fan 26 and the blower 30 are driven by a common motor 28.
  • Housing 50 surrounds the blower 30.
  • a shaft 52 drives the blower 30 and extends through an opening 100, 102 in the scroll housing 50 (see Figure 3).
  • the scroll housing 50 surrounds the blower 30, and causes air to be thrown radially outwardly and into a discharge conduit 100.
  • Discharge conduit 100 delivers the conditioned air through louvers 44, and outwardly of a portion 36 of the front grill 34.
  • air conditioning unit While the invention is disclosed as an air conditioning unit, it should be understood that the present invention would also extend to a heat pump.
  • air conditioning unit should be interpreted to extend to heat pumps, which can operate in an air conditioning mode, or in a heating mode.
  • fluid connections are generally not shown in this figure, however, a worker or ordinary skill in the art would recognize how to fluidly connect the various components for delivering refrigerant through the air conditioning unit 20.
  • the scroll housing 50 includes a first part having a discharge chamber 58 generally surrounding the blower 30, and a second part 54 having an internal surface 56 that operates in conjunction with the surface 58 to deliver air downstream to a housing portion 60, and into the discharge passage 100.
  • the second housing portion 54 can be removed vertically. This allows the sub-assembly of the blower 30, motor 28, fan 26 and fan housing 152 to be removed as a one-piece sub-assembly.
  • the present invention facilitates maintenance and/or replacement of the sub-assembly 30/28/26.
  • a shaft passage for allowing passage of the shaft 52 is provided by curved portions 100 and 102 on the scroll housing components 50 and 54, respectively.
  • surfaces 112 and 110 are formed on the two scroll housing portion 54 and 50, respectively, to provide a generally air tight seal along those surfaces. Since the second housing portion 54 has an angled inner edge 120, it generally falls into a surface 122 of the housing 50 due to gravity. Thus, complex securement devices are not necessary.
  • a partition 200 is included in most window air conditioning units, as known.
  • the partition provides a seal between the outside environment and the inside environment.
  • the partition sits just on the outside face of the scroll housing 50.
  • the partition 200 is shown removed, although it would not actually be removed when the sub-assembly is removed. It is shown removed in this view such that the slot 202 that is included in the partition 200, can be seen.
  • the slot 202 allows the shaft of the sub-assembly to be pulled upwardly, without having to remove the partition.
  • Second housing 54 has the portion 120, which is not as rigid as the outer portion, nor as rigid as the housing portion 50.
  • a lip 204 is formed on the portion 120, and fits against a lip 206 on the housing portion 50.
  • the partition 200 backs up the lip portion 204 such that additional rigidity is provided to the portion 120. This prevents the portion 120 from contacting the blower 30, which could cause undesirable noise.
  • the housing portion 54 is removed from the housing portion 50. As mentioned above, there may not need to be any mechanical securement between the two, as gravity would tend to hold the two in place. However, some screws, etc., may also be utilized if necessary to prevent vibration, etc.
  • a sub-assembly of the blower 30, motor 28, and fan 26, along with the fan housing 52 can be removed as a one-piece item. Maintenance may then be performed, and a repaired sub- assembly re-inserted into the housing.

Abstract

L'invention se rapporte à une unité de climatisation comprenant un boîtier à volutes, ou un boîtier pour la soufflerie de l'évaporateur, formé de deux parties. Les deux parties comprennent un orifice permettant à l'arbre d'entraînement de s'avancer à l'intérieur du boîtier à volute. La soufflerie est entraînée par la même moteur que le ventilateur du condenseur. La séparation d'une partie du boîtier à volutes de l'autre, permet d'extraire l'ensemble composé du ventilateur, de son moteur et de la soufflerie sous forme de module monobloc à des fins de maintenance ou de réparation.
